(if they're on different properties).
This patch basically gets rid of (ui-related) hack where we was adding specific
'fake' enums for datatypes needing additional options.
That was done because of broken UI code - to summarize, 'align' code did not support
correctly layout mixing vertical and horizontal sub-layouts, in particular if
it was 'column-major'.
A complete rewrite of this align code has been done, so now we can use a more
sane UI code.
This new code fixes a tons of issues with previous one, which basically was epic-failing
in many non-basic cases (especially mixed columns and rows with column-dominant layout).
It basically no more relies over order of buttons declaration in the uiBlock, instead it
finds and stores spatial neighbors and uses that data to compute needed stitching.
See code comments for details.
New code seems to be roughly ten times slower than old one (for complex grouped layouts),
that is, about a few microsecconds per alignment group - this remains reasonable.
Also, ui-align code becomming rather big in itself, it was separated in
own new `interface_align.c` file.

Custom-data on newly created face data was often rotated.
Now the API doesn't copy data from adjacent loops when creating faces.
Most functions were already overwriting this anyway.
Since such decisions are better made at a higher level, now it's the responsibility of the caller.
This is really similar to what GPU module was already doing. There are number of
possible improvements still:
- Re-use allocated VAOs when requesting new ones instead of going to the trouble
of freeing VAO and then re-creating it again.
- Move VAO handling to GPU module.
Fixes T46589: OpenSubdiv crash with drivers
There is no real elegant solution here, ideally a modifier shall never *modify*
a source DM, but that would imply much better ways to ensure required data
is available in that source DM, which we do not have currently.
So instead, let's use brute force solution for now and always create a local copy
of our source DM, that we can modify to our heart content!
The bug header is wrong, the file contains the high pitched sound, but the bug that existed was that animation rendering did not use the high quality resampler, while audio mixdown does.
Blender uses the low quality resampler to be as little CPU consuming as possible.
Otherwise user may have a hard time understanding why their modifier is no more working
after they e.g. deleted some vertices... including the root one. ;)

Crash was happening due to OpenGL free from the non-main thread. Ideally we need
to implement somewhat delayed unused buffer free for OpenSubdiv similar to what we
are doing in GPU module.
We needed the 'background' feature here, since we never wait on those preview-generation tasks.
Note that it also simplifies the code, and as usual testing is needed here on all possible platforms...
With current code, in single-threaded context, a pool of task may never be executed
until one calls BLI_task_pool_work_and_wait() on it, this is not acceptable for
asynchronous tasks where you never want to actually lock the main thread.
This commits adds an extra thread in single-threaded case, and a new 'type' of pool,
such that one can create real background pools of tasks. See code for details.

In previous code, worker would exit in case it gets awoken from a condition_wait() and
task queue is empty. However, there may be spurious wake up (either due to pthread itself,
or to some race condition between workers) that would lead to wrongly exiting a worker before
we actually exit the whole scheduler. See code for more details.
Metas are scanning all scenes duplis,
which can go into particle systems without an initialized derived-mesh.
For now just do NULL check, its not correct but real fix is not fitting well with current design.
Brush.toggle_brush was allowed to be an invalid pointer,
it worked for the one operator that used it - but in general bad practice,
requiring a lookup on every access.
Ensure the pointer is kept valid now.
Fix for T46494 wasn't working properly when de-selecting faces,
adjacent faces would remain selected but have unselected edges.
Logic here is admittedly rather fragile since it relies on both
selection functions and flushing afterwards.
Certain shapes could trick the inside/outside test.
An edge between 2 planar faces could be selected for detecting face-flipping (which failed).
While this could be prevented by skipping those edges,
use a method which searches for the outer most face-loop, then check it faces the center.
Works totally similar to backdrop in the compositor.

Grabbing now doesn't 'jump' when shift is released (matching rotation modes).
This simplifies most logic for transform input,
where mouse input callbacks can choose to use the 'virtual' cursor,
which accounts for precision when shift is held.
Each time we setted the mass the own object gravity was divided by its
old mass (i.e you could convert you car in a flying DeLorean with a

A note will be included in release notes due to retro compability

Previously it was possible that same component will be tagged for update
again and again, making update flushing really slow. Now we'll store flag
whether component was fully tagged.
This is still temporary solution because ideally we should just support
partial updates, but that's for the future.
Gives around 10% speedup on file from jpbouza.
This behavior caused a double free.
Before when we duplicated an instance of a group the new instance keep the pointer of the group but was not added in the group instance list (normal).
And during the object deletion we tried to remove the object in the instance list but anyways if it failed decrement the reference count.
Set the group and the instance list to NULL in ProcessReplica avoid these kind of problems.
'Distance from Object' color/alpha/thickness modifiers without a target
object were raising a run-time exception although it is not considered an
error condition.
The reported crash was confirmed as a segmentation fault in std::sort().
The cause of the crash was traced down to a binary comparison function
that was not satisfying the so-called strict weak ordering requirements of
the C++ standard sorting function. Specifically, the comparison operator
has to return false when two objects are equivalent (i.e., comp(a, a) must
be false), but that requirement was not met.
Since the binary comparison operator in question could be a user-defined
Python function, here a safety measure is implemented in the C++ layer to
make sure the aforementioned requirement is always satisfied.
Bug introduced in 583fa7d1e, KX_GameObject.setActionFrame can make BL_Action::m_starttime negative. But in BL_Action::Update m_starttime is set to the current time if it's negative.
To fix it we use a boolean BL_Action::m_initializedTime to know if we should initialize the time in BL_Action::Update, it's more stable than comparing times.

Shutter curve now can be controlled using curve mapping widget in the motion
blur panel in Render buttons. Only mapping from 0..1 by x axis are allowed,
Y values will be normalized to fill in 0..1 space as well automatically.
Y values of 0 means fully closed shutter, Y values of 1 means fully opened
shutter.
Default mapping is set to old behavior when shutter opens and closes instantly.
This shutter mapping curve could easily be used by any other render engine by
accessing scene.render.motion_blur_shutter_curve.

Previously shutter was instantly opening, staying opened for the shutter time
period of time and then instantly closing. This isn't quite how real cameras
are working, where shutter is opening with some curve. Now it is possible to
define user curve for how much shutter is opened across the sampling period
of time.
This could be used for example to make motion blur trails softer.
Previously curve mapping was always setting to only a single slope which then
was symmetrizied by a tools (such as brush or compositing).
With this change it's possible to set curve to symmetrical slopes as a part
of preset.
This appears to be really common workflow when you stabilize shot to make compo
easier (roto, some effects and so) and then re-introduce the motion back.
Surely it's doable with some magic nodes and manual network for transforming
but such workflow is too common in VFX to resist adding one small option in
single node for this.
Opening a tmp window on a 4K display with virtual pixelsize set to double results in a too small window. For Retina this seems to be handled on GHOST level already, so multiply by virtual pixelsize only.
This patch makes independant the override camera zoom and the default camera object zoom. The override zoom is 2.0f and the camera object zoom is computed with the RegionView3D camera zoom.
These features are only used for the embedded BGE, so there's no compatibility issues with the blenderplayer.
I let the override zoom with a setter to allow later to create an override camera in blenderplayer easily.
Tested with the 3 framing modes in embedded and standalone.
I made this patch to declared a python list without converting all elements in python object (too slow) or use a CListValue which required CValue items (too expensive in memory). In the case of a big list of points like a collision contacts points list, to use a CListValue we must implement a new class based on CValue for 3D vector to create a python proxy even if mathutils do it perfectly, we must also convert all points (frequently ~100 points) when fill the CListValue even if the list is not used (in the case of the collision callback). The easy way is to use callback (it doesn't worth to do an inheritance) which convert the item in PyObject only during an acces.
5 callbacks are used :
- Check if the list is valid = allow acces (like PyObjectPlus.invalid)
- Get the list size
- Get an item in the list by index.
- Get an item name in the list by index (used for operator `list["name"]`)
- Set an item in the list at the index position.
All of these callback take as first argument the client instance.
Why do we use a void * for the client instance ? : In KX_PythonInitTypes.cpp we have to initialize each python inherited class, if we use a template (the only other way) we must add this class each time we use a new type with in KX_PythonInitTypes.cpp
To check if the list can be accessed from python by the user, we check if the python proxy, which is the `m_base` member, is still a valid proxy like in PyObjectPlus. But we can use a callback for more control of user access (e.g a list of collision point invalidate a frame later, in this case no real python owner).
This python list is easily defined with :
```
CPythonCallBackList(
void *client, // The client instance
PyObject *base, // The python instance which owned this list, used to know if the list is valid (like in KX_PythonSeq)
bool (*checkValid)(void *), // A callback to check if this list is till valid (optional)
int (*getSize)(void *), // A callback to get size
PyObject *(*getItem)(void *, int), // A callback to get an item
const char *(*getItemName)(void *, int), // A callback to get an item name (optional) use for acces by string key
bool (*setItem)(void *, int, PyObject *) // A callback to set an item (optional)
)
```
To show its usecase i replaced the odd KX_PythonSeq, it modify KX_Gameobject.sensors/controllers/actuators, SCA_IController.sensors/actuators and BL_ArmatureObject.constraints/channels.
Example : {F245193}, See message in console, press R to erase the object and see invalid proxy error message.

Previously, a warning was added to provide feedback to users trying to change the values
of driven properties why their edits would not have any effect on the propeerty. However,
it turned out that instead of only showing up when the user tried to increment/decrement/slide
the property's value, it was also firing everytime they were trying to edit the expression.
That however is not what we want at all!
This fix assumes that BUTTON_STATE_TEXT_EDITING is used for expression editing, and
BUTTON_STATE_NUM_EDITING (or everything else) refers to the user trying to adjust the
value normally.
When using the "Current Frame" options for these operators, the Cursor X value
will now be used instead of the current frame. Perhaps the labels could be changed
too, but for now, I guess this will be good enough.
When the "Use Y" option in the Copy Rotation constraint is disabled, the constraint
behaves eratically when rotating all the target on all axes at the same time.
This is partially to be expected due to the way that euler rotations work
(i.e. the rotation orders stuff - you should use a rotation order based on most to
least important/significant rotations). Hence, by locking Y, you're causing accuracy
problems for Z.
What was not expected though was that changing the rotation orders on the objects
involved (for the record, it's the constraint owner that counts) did nothing.
It turns out that for objects, the rotation order settings were getting ignored!
This commit fixes this problem, and this particular case can be resolved by using
"XZY".
Notes:
* Since all object constraints were previously working on the assumption that they
used XYZ (default) order, it is possible that this change may have the unintended
consequence of changing the behaviour of some rigs which relied on the buggy
behaviour. Hopefully this will be a rare occurrence.
When working is the Graph Editor it can be very important to be able to work with fractions
(sub integers), especially when working with Drivers. Currently the "Cursor Y" is hooked up
to "cursor_position_y" which allows fractions but "Cursor X" is directly hooked up to
"frame_current" which is an integer.
This commit adds initial support for this feature.
* When in Drivers mode, the x-part of the cursor is mapped to a new "cursor_position_x"
value which can have fractional values. Animation mode however remains mapped to frame_current
* This commit only adds the UI/property/drawing tweaks needed to support this.
Many operators still need to be modified to consider this value instead of the
current frame, for this to be more useful.
Sometimes the timeline header didn't update after time-scrubbing in the graph
editor ends, leaving the "Pause" button visible until the next refresh of the
timeline (e.g. on mouse over)
Load driver dynamically at runtime instead of weak-linking the
3Dconnexion framework. Driver no longer needed at build time!
Works with really old drivers (as in PowerMac old), more recent

Previously it would save packed file(s),

Add image.packed_files[...].save() so you can save packed files if its needed.
Idea is, instead of ignoring completely missing linked datablocks, to
create void placeholders for them.
That way, you can work on your file, save it, and find again your missing data once
lib becomes available again. Or you can edit missing lib's path (in Outliner),
save and reload the file, and you are done.
Also, Outliner now shows broken libraries (and placeholders) with a 'broken lib' icon.
Future plans are also to be able to relocate missing libs and reload them at runtime.
Code notes:
- Placeholder ID is just a regular datablock of same type as expected linked one,
with 'default' data, and a LIB_MISSING bitflag set.
- To allow creation of such datablocks, creation of datablocks in BKE was split in two step:
+ Allocation of memory itself.
+ Setting of all internal data to default values.

Even if the weights are normalized, the weighted sum of normalized vectors

This probably was not a big issue in most cases, since we usually interpolate
similar vectors here - but still!
The final stage of the process (copying/interpolating new dst cddata from src cddata)

setDrawOptions should be ommitable and fully VBOfialbe (?) in the

Filenames over 128 chars would crash.

this was only used in one place and isn't all that re-usable.

linking API funcs would use 'name, idcode', when all other code here uses

Also, use 'name' arg name when we expect a bare name, without the prepended ID code, and
'idname' arg name when we expect a complete ID name.
And here too, idcode shall be short, not int!
Used old (2.49 era) filled style for drawing here, with white color and
alpha blending.

New code loops much less, does re-open & close .blend files for each data type,

Main idea is to store libraries & datablocks to link in a dedicated struct, in a way
that avoids too much looping, and also allows to search for a single datablock in several libraries.
Here again, no change is expected in current behavior of link/append tool, please report
if anything goes different!
This commits does mostly two things:
* Get rid of bContext parameter: I can see no real good reason to pass such a high-level data
to such low-level code... It also makes it more difficult to call when you do not have
a context available.
* Cleanup the instantiating part.
Last point is the most risky - previous code was sometimes quite confusing and hard to follow,
from tests nothing behaves differently in new code, but some hidden corner case may show up.
Anyway, no change in behavior is expected from this commit, if it happens please file a bugreport!
It turns out libGL from Intel crashes when calling glxewInit (where mesa, nvidia work fine),
unfortunately the only option without making larger changes to glew,
is to inline the parts of glew we're using - before the glx context is created.
Root of the issue is that we do not re-read lib data blocks and ID placholders (ID_ID bheads)
in undo context (in `blo_read_file_internal`), because `BLO_read_from_memfile` copies
lib datablocks and Main data directly from oldmain.
The idea being, linked data do not change from undo/redo.
This is valid as long as linked data was not changed by the undo step - but if some
was deleted or localized, it will be missing from oldmain, leading to data loss
(note that does not only concern objects, all linkable data types can be affected,
at least in theory).
This commit addresses that issue by carefully mixing reuse of needed data from oldmain,
and "normal" re-reading of missing one. Makes us swimming in some rather dark waters,
and gives a rather non-easy-to-follow code, but it seems to work quite well,
and only other solution would be to get rid of that optimization
(not re-reading all libs on undo/redo), which is not acceptable.
Also, thanks to @carlosdp for initial investigation of the issue.

Ray direction is assumed to be normalized in such areas as scaling intersection

Now normalization will happen on surface bounce, which could be a bit of a waste

BSDF seems to give guaranteed normalized direction.
Issue was caused by wrong intersection distance scaling on instance pop,
which could cause intersection distance to become zero, confusing following
intersection checks.
Looks like instancing of smoke sim is not supported at all

But it should not crash - code was adding temp 'fromdupli' base to the delayed

Nice to backport this to 2.76 I think.
This patch makes it possible to zero out angular velocity. tiny angular
velocities may cause instabilities, according to the discussion in T41943,
so they are mapped to (0, 0, 0) instead.
It also applies the same reasoning to the linear velocity, unifying the
different approaches.

Transition strips in the NLA should always stick to whatever strips are beside it,
and are allowed to grow/shrink as needed to achieve this. Previously the code here
was only checking if the neighbouring strips started encroaching on the transition,
but not whether the transition needed to grow to fill a gap. It was also just
moving all strips when there was insufficient space, even though that would alter
timing down the track.
Now transition strip resizing works as follows:
* It will grow/shrink as necessary to absorb any changes in the length of its neighbours
instead of shunting everything around to maintain its length
* If the neighbour has been resized by an amount greater than the transition's length,
all the strips will need to be shunted away to make way for the neighbour. In this
case, the transition will shrink down to being 1 frame long to ensure that it is
still visible (so that it can be removed if necessary).
The "tweak user" flag used to flag strips using the same action as the active strip
was not getting set on other strips that live on the same track as the active one.
Strips with this flag set are shown with a red colour to indicate that editing the
action may have the unintended consequence of modifying another strip.
Duplicate wasn't updating links,
so duplicatinvg a objects would still point to the originals for curve-taper, texmesh, drivers.
Use generic id-looper to handle replacing data.
- BLI_current_working_dir's return value must be checked, since it may fail.
- BLI_current_working_dir now behaves like getcwd, where a too-small target will return failure.
- avoid buffer overrun with BLI_path_cwd, by taking a maxlen arg.
I have removed the m_pHitObject, m_xray and m_testPropName and replace them by a temporary struct "RayCastData" which contains these datas and a collision mask. Finally i add a collision mask argument in the python function "rayCast" :
```
rayCast(to, from, dist, prop, face, xray, poly, mask)
```
It can be useful to hit only object which are on the right colision layer. for example if you have hitbox for a charater or vehicle you don't want to hit it with raycast.

This func is long enough, there's no real need to make it even longer with
verbose local varnames and multi-line for loops...
Also, avoid mono-leters names as well for data pointers.
We now keep actions around when they are finished playing so scripts can
still get access to information such as the current frame. Playing a new
action in the same layer still overwrites the previous action as before this
commit. Using an explicit KX_GameObject.stopAction() will free the memory. The
action is also freed when the KX_GameObject is freed as before.
We now have to explicitely enure tesselation of DMs when we need it.
Notes: Maybe we could use looptris here as well?
Not a regression (bug already present in 2.75, but not 2.74), nice to backport to 2.76 nontheless.
Own regression caused by fix for T46067,
edit-mode bvh only contained unselected faces.
This commit adds support for an edit-mode bvh containing all faces.
Depsgraph customdata flag was set on the parent,
then cleared once the parent object was handled.
This is initialized to zero for new nodes, no need to clear.
Expose our `BKE_image_load_exists` feature through an optional parameter to `Image.load()`.
Extend `image_utils.load_image()` with two optional parameters, to return existing image datablock

Needed by incomming 'import images as planes' addon enhancement.
Also, fix own stupidity, no need to define ID callback in case we only have objects,
calling code knows to fallback to `foreachObjectLink()` when `foreachIDLink()` is missing...
Our version of clang fails with latest SDK. It's not really clear if such
change will disable openmp or not (-fopenmp doesn't throw an error, but
it might be a silent fail).
In any case, builds without OpenMP is better than no builds at all.\
- Match layout from stamp buffer (note last so it can wrap)
- Correct vertical spacing (didn't take decender into account)
- Use U.pixelsize when setting font-size.
It would simply remove default units (in most case), cannot see any good reason for such behavior?
Might work in case default unit is the only one present, but breaks consistency (and it may not be
always obvious for user which unit it is). Comes from original patch from five years ago, rB7d8f0fce.
This will break keyboard-setting of values, e.g. '2m 33.4cm' would become '2 33.4cm',
totally useless and invalid entry!
Issue was caused by changed function signature. This is still not really full
support of new OSL API since we don't store anything in the derivatives which
could confuse mipmapping.
Would write 1.04 seconds as `00:00:01,40` instead of `00:00:01,040`...
Anyway, we already have BLI API for timecodes, much better to add
SubRip timecode format there, heavily simplifies code.
To be backported to final 2.76.
Instead of offsetting along normals, smooth positions are now
calculated on a sphere defined by the vertices and their normals.
This removes visible seams along original edges, which were common previously.
E.g. trackball-arrows (R-R) were no more visible.
Caused by wrong cast of an array from int to float, we need an int version of those helpers (`glTranslatenxv`) too.
Broken by font wrap commit rBf2341f829654c4dc97, there was actually two things here:
* Using non-initialized color (which lead to transparent drawing...), we need to use new
`blf_draw_buffer__start/end` helpers here too, made them shared internally.
* Using `draw_str_i18n_nbr` as `draw_str[i]` length, ugh! That's the number of utf8 glyphs of
translated string, not the length of untranslated string!
This fix must be backported to final 2.76.
Cleanup and rework a bit text_cursor_set_to_pos_wrapped(), it did not handle correctly negative y valuesi,
because it was only checking lines starting from first visible one.
Mostly, we now directly get line matching given y position (be it an invisible one) from the helper
(renamed `get_line_pos_wrapped()`), instead of first visible one, which allows us to get rid of
additional complexity of looping over next lines until we find correct one.
This code remains rather complex to follow, added some asserts to ensure everything works as expected,
and tested it rather seriously, but DO NOT backport this to 2.76!
If t->mode remains edge/vert slide, restoreTransObjects() ends up calling
projectVert/EdgeSlideData(), which tries to access invalid customdata...
Not sure why we call again restoreTransObjects() and resetTransRestrictions() here tbh,
but safer not to change that for now.
Should be backported to 2.76 if possible.
More precise description of the issue: Clicking on the right side of a num-slider button with Continuous Grab enabled sometimes caused cursor to jump to the inner value indicator even though text editing was started.
Happened because data->ungrab_mval wasn't reset correctly after dragging.
Windows-only bug, mmap & co are not threadsafe by default on this platform, so we have to add a dedicated
spinlock for them in win32.
Note that we may try to get rid of those mmap later, but not for 2.76!

The issue was introduced by original Cycles point density support commit,
it lead to a constant density of 1 for object verticies point density source.
Mostly added missing :arg: clauses -- these caused the :type:-clauses
that were already in the RST files to be hidden from the output HTML.
I also fixed some argument types from 'list' to 'Vector' where applicable
and corrected some obvious mistakes.
We need custom context here, those are often very short names so context collision is pretty easy.
Also some minor changes (and avoid shadowing varnames)...
This is a mere bandage, that whole area is known broken anyway, but at least it should prevent the crash.
Note that that kind of stuff (the efd->index being a pointer) is really bad practice imho...
Should be backported to final 2.76.
Notes:
- There is still some bvh cache code, but that is from the engines initial commit, we might clean this up further or keep it.
- Changes in util_cache.h/.c are kept, this might be re-used in the future.
This removes the BVH cache feature from the UI, underlying code will be removed in a separate commit.
The BVH cache was added before we had a multi-threaded BVH build, and a lot of other optimizations were done since then, which makes this not useful anymore.
Fix T46162.
- measure extents from mesh center instead of origin.
- use clamping method, guaranteed not to flip the input vectors direction.
- use cage coords when available (since knife operates on the cage).
So now the following OSL versions are supported (at least for compilation):
- 1.5 with closure alignment patch applied
- 1.6.8 release
- 1.7 development version from latest git
Calling event handling recursively during window live resize is problematic,
the code wasn't designed to do that. Instead postpone event handling until
after live resize.
- Custom scale:
Avoids having multiple custom-shapes at different sizes.
- Option not to use bones length:
So changes in edit-mode don't resize the custom-shape.
This was broken since ages I think, did not really hurt since we usually never use libs' names
to access them. Rather bad behavior however, breaking a ground rule of our ID system!
And no real reason to add new libraries to new (split) Main at all, libraries are
never considered linked datablocks, which means they should always be in 'main' Main->library list.
Not a regression, but should be included in 2.76 imho.
- Removed relation labels, since these mostly just reflect connected nodes, and also appear too far off the edge lines
- Draw cyclic links in dark red
- Slightly thicker edges and larger margins
Compositing might make main thread so busy that animation is considered done due to duration before final position is reached.
Also added check to avoid unnecessary redraws.
Issue is, when 'Rotate Aroud Selection' is set, in Edit mode we do a fake transform operation
to get center point around which to rotate. For curves, most transform operations involve
a check of handle types. For now, added 'TFM_DUMMY' as an exception here.
Think it would be best to actually undo those changes in case of cancelled operation,
but this is much more involved, while this fix is safe enough to be included in final 2.76.
This wasn't visible with default settings,
but caused problems w/ pie-menu's & manually adjusted theme font-size.
Now only draw from the bound-box top w/ word-wrap enabled.
Adjusts view after mouse/border selection if some selected items are out of view bounds.
To get as much of the selection into view as possible, this adjusts view first for the last, then for the first element in the selection.
Also, if region is pretty small, view adjustment is skipped, as otherwise the view is focused on the first element only, which isn't really useful IMHO.
Maybe not so nice: Since we do two view alignment iterations, UI_view2d_curRect_validate, which is a rather big function *might* be called twice under certain circumstances (border select & total size of selected elements is exceeds view bounds). I think that's totally acceptable though.
Basically, after border selecting, a wrong file was selected by using arrow keys if the screen was scrolled a bit vertically. Reason was that we didn't use correct view space coordinates but region space coordinates for measuring distance from mouse to first/last file in selection after border select.
Added some extra seed to the hash, so it's now less likely to give repetitive
patters at values around zero.
This will change distribution of bricks for existing files. but it's something
inevitable.
- Adds support for word wrapping to Blender's BLF font library.
- Splits lines when width limit is reached or on explicit \n newlines.
Details:
- Word wrapping is used when `BLF_WORD_WRAP` flag is enabled.
- There is a single loop to handle line wrapping,
this runs callback, passing in a substring,
this way we can avoid code-duplication for all word-wrapped
versions of functions... OR... avoid having to add support
for word-wrapping directly into each function.
- The `ResultBLF` struct was added to be able to get the number
of wrapped lines, when calling otherwise unrelated functions
such as `BLF_draw/BLF_width/BLF_boundbox`,
which can be passed as the last argument to `BLF_*_ex()` functions.
- The `ResultBLF` struct is used to store the result of drawing
(currently only the number of lines wrapped, and the width).
Epsilon was quite arbitrary for GPU, replaced with checking for zero-sized faces.
It should solve both original report and the new one. After the release we can check
why GPU doesn't produce accurate math here and go to the root of the issue.
The user interface was ignoring the precision step size for degrees,
making all rotation inputs drag by a 100th of a degree.
Now use a 10th of a degree instead.
SCons didn't pass `-DWITH_AUDASPACE` to the compiler, so it skipped the
instantiation of the "aud" Python module. This caused a crash of the BGE,
which did get the `-DWITH_AUDASPACE` directive, and expected that module
to exist.

As of this release we're able to navigate with the keyboard in the filebrowsing area. The button caption is changing to an appropriate string whenever a new entry is selected.

For now simply show warning in the interface and fallback to regular subsurf
code. Supporting OpenSubdiv in edit mode in possible but not high priority
currently.
The issue was caused by some special tricks needed to compile OpenSubdiv shader
which was using stupid check whether geometry shader is used or not.
Now made it more explicit call whether special OpenSubdiv trickery is needed or
not.
Its not ideal solution, but it's not really easy to do a proper solution for
this, because while we can do half of the work with if-defs in the shader code
but we'll still need to somewhat define layout of the input blocks which isn't
really doable with current shader version we're using.
Disable Intel cards for until we'll go to the root of the issue of the crash.
This will take a bit, so being so close to the release we go safe and disable

This could be bypassed by setting OPENSUBDIV_ALLOW_INTEL environment variable.

Supporting those (really) old GPUs requires us to make shaders more
expensive by converting between real and scaled coordinates and be wary
of such conversion caveats when handling uv coordinates in shaders. Not
worth the cost for supporting hardware that old.
Also they did not work when using blender -R from
command line in 64-bit systems.
Issue was checking for wrong define which would
cause code to detect if the blender executable
functions under 32 bit emulation.
For 64bit executables this is false, leading
blender to believe we are operating under a 32bit
system, and registration would try to register
the 32bit thumbnailer.
This 32 bit dll is (correctly) missing for local
installs and from the new installer, thus no thumbnails.
Using the global scheduler here is not a really good idea - `filelist_cache_previewf()` is not a short task
that run once, but it's a loop that keeps cheking for work in a TODO queue. This means it won't quickly allow other tasks
to start, so it should not be in the global scheduler.
In fact, asynchronous tasks (that is, tasks that will live for quite a bit of time, and often sleep a lot) should never use
global scheduler, they would steal computing resources from heavy-duty, short-time living ones - and possibly even completely
stall threaded tasks (if all worker threads are executing long-life tasks...).
We could probably even completely bypass the scheduler/task thing here (and directly use threads), but it does not have
that much of an over-head, and still offers easy handling of threading stuff...
Added a helper that ensures a bbox has some non-NULL dimension along all its axes.
Also, fixed some (rather unlikely) NULL dereference cases (though it should not in this context,

the correct width/height into glReadPixels; the result may not

Deviding two ints together never yields a float... Also, logic of various proxies size corrections was quite broken.
Now we should always get the same (relative) size of text whatever proxy setting/render scale is chosen.

Volume label on Windows was request from T46083, makes Blender more in line

And now, we automatically set name of recent entries from the bookmarks, if path

Due to how we find kmi to remove and kmi to add when patching final keymap with user defines,
we could actually end up with same kmi for both, see comments in code for details.
Note that it may be a good idea to make user-defined customizations specific to a given base keymap,
instead of applying them blindly?
Since Blender internal strings are UTF8, changed the initialization

We were still using main borwser's FileDirEntryArr to own memory of entries currently in cache.
That was OK for common caching operation, but if was not released when clearing cache!
Nothing dramatic, since that was cleared too, but less often, so e.g. by changing sorting
options you could pile up more and more no-more-used entries there...
Anyway, there is no reason to do that, much more sound and clean to keep everything
cache-related in dedicated FileDirEntryCache struct.
This means main borwser's FileDirEntryArr is now always expected to not store any actual entry!
Note: this can probably be cleaned up a bit more, but would wait after 2.76 for this!

To reproduce the crash:
* Add some shapekeys to default cube.
* Add at least on driver (can be default empty one) to a shapekey value.
* **Make this driver visible in Outliner**.
* Delete all shapekeys.
* Undo.
* Crash.
Root of the issue is outliner reading code in `blo_lib_link_screen_restore()`,
which would try to `restore_pointer_by_name()` for all `TreeStoreElement->id` pointers.
Thing is, those id pointers are not always IDs, they can be animdata, sequence, RNA struct/property...
That's really not so great design, but also has reasons like size of the struct, we have to live with it.
So now:
* TreeStoreElement->type defines are braught back into DNA.
* There we also define a `TSE_IS_REAL_ID` macro to check whether a given TreeStoreElement actually stores an ID pointer or not.
* And in Outliner read code we only try to retore pointers by name for actual ID ones, and set the others to default NULL value.
Also, added clear comment to TSE types that do not store a real ID pointer!
From Gooseberry team request indirect libs were also added at root of 'BlendFile' Outliner view,
but that allowed edition of their path, which is useless...

Now, ctrl+wheel for cycling tabs is passed to hovered button if it supports cycling values (RNA menus, color/row/number/slider buttons, list boxes)
This might feel a bit glitchy if ctrl+wheel is used to cycle tabs and in newly opened tab, a button with cycling support is under the mouse, which will get mouse input from this point on instead of region. Think this is still better than old behavior.
When a modifier was animated by a NLA strip, this animation was not working when using
the old depsgraph. This was because the code which checks if a NLA strip affects any
modifiers was missing - specifically, it was originally left out as it was thought
that it was unlikely that many users would need this, but adding in those checks
would have a (slight) negative effect files where there are heaps of NLA strips
but modifiers animated this way were absent.
The new depsgraph however doesn't suffer from this problem, as these sorts of checks
need ot be built into the graph-building stage for everything to work, so these links
had already been added.
This was simply broken for vertex case (indexing loop normals with vert indices...).
Turns out to be rather verbose to replace on-the-fly zero normals by default ones correctly,
and do not want to make a full copy of the given custom normals array, so now this one is
editied in place (replacing zero vectors by correct default normals). Don't think this
could be a serious issue anyway.
It can't be simply removed in cases when it's connected to input which is
different from Normal. This is because the input wouldn't be connected to
default Normal geometry input, possibly breaking shading setup.
The fix is not really ideal, but should work at least.
This fixes skin having too much glossy reflection in the file from T46013.
Initial idea was to optimize calculation a bit by skipping calculation of actual
triangle edges and use vector from ray origin to triangles. In practice this
optimization didn't quite work in cases when origin point is too close to the
triangle.
Let's do 2.76 with a bit more complicated calculation, still looking into exact
reasons why watertight intersections fails in certain cases, but actual fix might
bit be ready so soon.
This fixes wrong eyes on the lady from T46013.
That one was hairy... To summarize:
* We were setting Bone.head/tail (aka **local** rest location of bone) from EditBone data, using **EditBone's parent computed armature space**.
* We use those local head/tail to define Bone's restpose (in `BKE_armature_where_is_bone()`), using **Bone's parent armature space** (aka parent's arm_mat).
* Because of bone's roll nightmare, the two above parent's matrices will often not be the same.
In an ideal world, this should not affect locations (head/tail), but in real world of float it does - noticeably, in some extreme cases.
So! This commit cleans up things a bit (`fix_bonelist_roll()` was already doing much more than just fixing roll mess, has been renamed
to `armature_finalize_restpose()`), and ensures we do use (final!) parent's arm_mat local space to compute children's local head/tail as well.
This allows us to avoid too much imprecision here.
Checked the patch also with a complete Victor's rig from Gooseberry, seems to have no nasty side effects - fingers crossed!
`fix_bonelist_roll()` is already recursive, and was calling recursive `BKE_armature_where_is_bone()` twice!
Changed `BKE_armature_where_is_bone()` to controll whether we recurse over children or not.
With full Victor's rig, we gain 16% in `ED_armature_from_edit()` (from 31ms to 26ms).
With a dummy test-case 100 bones chain, we gain 80% in `ED_armature_from_edit()` (from 1.25ms to 0.25ms).
Not crucial, but still worth it. ;)
The issue was caused by wrong detection whether number of verticies
changed or not. Basically, it wasn't working correct in cases when
number of verticies is increasing compared to the current frame.
This causes no change in behavior, since code was alreadying doing
a no-op in bmesh_edge_separate if the edge is a boundary.
But it tripped an assert, annoying in debug builds.
We want to leave assert in bmesh_edge_separate in case callers
expect there to be separate loops after this always.
So putting test in caller.
(Same worry about bmesh_urmv_loop? I checked callers and they
appear OK to me - they deal with the no-op return.)
This isn't really complete fix, complete fix would require calculating
derivatives via OIIO API, but supporting this will either end up with
some code duplication or will require some non really safe changes at
this release cycle.
The documentation for bge.render.{setWindowSize,setFullScreen,getFullScreen}
did not mention that those functions are no-ops when using the Blender-
embedded player.
Extensions such as ".tar.gz" are now also supported. Before this patch,
ensure_ext('demo.tar.gz', '.tar.gz') would return 'demo.tar.tar.gz'.
This results in issues with the `ExportHelper` mix-in class; clicking
an existing file in the file dialogue warns about overwriting it
(highlighting the input box in red), but then saves to a different
file.
Also added a unit test for the new behaviour.

The detection of needed sharp edges (based on given loop normals) would not fully work
on first run in case we started with a complete smooth cyclic loop fan (edge between

get_keyframe_extents() would add an extra frame in case of mono-key fcurves in selected set...
Now do the 'not same start/end frames' check later, and also use floor/ceil instead of round

Since data transfer when called from this tool has reversed behavior (it transfers **towards**

Using the brand new and much simple float pixels accessor to PreviewImage now.

Raw int pixels can be nice in some cases (much less memory used), but converting to/from float values

* Generating and searching for a brush take a mode argument now. Needed

Basically filtering was happening twice, first time by applying weights of EWA

Primary goal of this commit is to fix an annoying issue - when processing and saving .blend
files in background mode you lose their thumbnails, since it can only be generated with
an OpenGL context.
Solution to that is to read .blend thumbnail while reading .blend file (only done in background
mode currently), and store it in Main struct.
Also, this lead to removing .blend file reading code from thumb_blend (no need to have doublons).
We now have a small interface in regular reading code area, which keeps it reasonbaly light
by only reading/parsing header info, and first few BHead blocks.
This makes code reading .blend thumbnail about 3 to 4 times slower than previous highly specialized
one in blend_thumb.c, but overall thumbnail generation of a big .blend files folder only grows
of about 1%, think we can bare with it.
Finally, since thumbnail is now optionally stored in Main struct, it makes it easy to allow user
to define their own custom one (instead of auto-generated one). RNA API for this was not added though,
accessing that kind of .blend meta-data has to be rethought a bit on a bigger level first.

Issue was caused by blender internal accessing data from DNA during rendering.
There's no simple solution to make stuff thread safe, so for now simply restart
rendering on frame update.
The issue was caused by uninitialized ray used for composite and AO evaluation.
Can;t really think of "proper" ray configuration here, it's all a bit arbitrary
but think initializing the ray in a way so we look at the surface in a negative
normal direction is much better alternative to uninitialized ray.
Open for alternative suggestions tho.
This is more like a workaround to prevent obvious cases fail, but in theory
if some other area will start updating object for subframes blender will
crash again.
Perhaps proper way to solve this will be to copy objects for subframe updates.
The issue was in fact caused by both preview and viewport renderers affecting
on the default material, conflicting with each other.
Preview render doesn't really need default material, so we can safely skip it's
initialization in the render pipeline for preview rendering.
Don't force re-distribution of cached particle systems, this doesn't
cause actual evaluation of particles and there was a reason why particles
are baked actually..
This isn't a Blender issue and the same bug happens with official OpenSubdiv
examples. For until it's either worked around from OpenSubdiv side or fixed
in the driver we'll force disable GLSL Compute for AMD hardware.
Uniform block data layout was different on CPU and GPU which caused wrong
data being used from shader.
In theory using layout(std140) is what we need to do, but for some reason
such layout specifier is being ignored. This is probably caused by the way
how we exploit extensions from older version of glsl.
For until we've upgraded our glsl pipeline used different approach which
is basically about removing unused fields form the struct manual in hope
that it'll keep memory layout consistent for both CPU and GPU.
This seems to work so far for both NVidia GTX580 and AMD FirePro W8000
here in the studio.
It was possible to navigate into an unused temp screen
(using Ctrl+Arrow keys), but there was no way to navigate back out.
Now Ctrl+Arrows skips temp screens, and remove the ability to navigate away from a temp screen from RNA.
This reverts commit 1ed1f2f3ab.
Waiting 10 seconds to change view isn't practical.
Further it expose issues where users can attempt to activate tools during view motion,
Some work, others give issues, this just isn't going to be properly supported.
View animation features are fine, but this isn't the purpose of the smooth-view option.
This is a bit tricky one -- ideally viewport should detect whether alpha is used
in the shader tree and if so do separate viewport pass for that objects. But in
practice it's really tricky to detect whether alpha is affected by shader or not
without evaluating the tree for all possible input values. We also can't assume
that alpha might always be affected because it'll slow viewport drawing down.
For until some smart solution is found simply expose alpha blending mode used
by the viewport. It could be found below the Viewport Color settings.
By popular request, restored the ability to shift-click on the X (unlink) button
to unlink the action (from the active action slot), clear the Fake User, and
also remove the NLA-stashed copy (only works for the current object/NLA stack though).
Forgot to increase the size of the string buffer in b88d8916e4
While this wouldn't have caused problems in most cases (since most modifier names
are short), in the rare event that a long modifier name exists, the buffer may have
ended up being truncated prematurely, causing the wrong FCurves to get matched.
It's hopefully no longer needed, at least not needed for as long as
single ptex face corresponds to a single patch which should be always
correct for uniform subdivisions as far as i know.
Implementation is less optimal compared to non-opensubdiv drawing but
it is now as good as we can do it without affecting on how patches are
being created by OpenSubdiv.
By using getAnimRecordFrame(), game developers have access to the frame
number used by the "Record animation" feature. This enables them to
record additional information in Blender's F-Curves and ensuring perfect
synchronization with the information already recorded by Blender.
The setAnimRecordFrame() can be used to change the frame number at which
animations are recorded, for example to introduce delays the recording that
do not require delays in the actual game/simulation run.
The getter/setter functions in KX_KetsjiEngine are not directly named after
property they access (m_currentFrame). I found "current frame" to be too
vague for a public interface, hence chose a more descriptive name.

Use vertex varying data which gives better approximation of normals.
Still not ideal but should be closer for higher poly meshes to correct
normal.
The only way to have proper smooth normals seems to be to implement
patch evaluation in tessellation shader, but that's a bit PITA with
current GLSL usage in our draw code.
* Fix BLI_file_touch, used to add one dummy byte ((unsigned char)EOF) to empty files!
* Get rid of static global temp string in WIN32 area (very bad, and useless!).
* Get rid of paranoid NULL checks in WIN32's BLI_gzopen().
* Add non-relative filename asserts to WIN32 file operations too.
* ifdef-out BLI_move and BLI_create_symlink, unused (and the later is not even implemented for windows).
Partly based on patch and points raised by Jason Wilkins (jwilkins) in T32870, thanks!
The issue was caused by some numeric instability in triangle intersection which
was visible on avx2 CPUs and GPUs (at least sm_20 here) but maybe some others
too.
Committing rather a workaround for now to be safe for the release, still need
some investigation.
